The transplantation occurred between newborn mice (assuming same age); thus, age is not a variable. Since it's not a variable, it's not something that would affect the thymuses. Does that make sense? It's a tricky question and I got this one wrong.

Your question does make sense. The other experiments show that the age of the animals is an important factor in the development and functions of the thymus. However, for this experiment alone, age is not a variable.

How is the transplant not a variable? The whole point was to see if the immune system would continue to work in the other mouse even after the transplant had taken place
